' ADnING-mcnmii Specification of Letters Patent. Patented July 22, 19111 Application filed February 21, 1912. Serial No. 679,103.

To all whom it mag concern."

Be it known that I, Lian 1. -DARsY, a oitizen of the United States, residing at Newark, in the county of Essex and State 5. of New Jersey, have invented certain new.

I anduscfut Improvements. in Adding-Ma I chines; and I do hereby-declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains reference being ,to make and use the same,

had to the accompanying-drawin and to characters of reference marke thereon,- which form a part of this specification. This invention relates, generally, to im- :provements in adding and printing ma-I -'c hines; and, the invention relates, more par ticularly; to a novel machine for registering, recording and printing figures, the aggregate sum of addition offthe figures printed being -likewise recorded upon a series of registering as adding disks, "so that such sum of additicifcari'lbe readily-printed at the end ofthe column ofi'printed figures which areto be :ui'dedi" t? 4 i The present invention has for ,its' prime cipal objectltol provide a combined adding} andprinting'm achi acter above 'stated, the niechamsm of which is simple and operates most eflicintly'; and; furthermore, the purpose of this invention is to provide an adding -machine provided with two: sets'ofidepressible keys, one set of keys being employed for laterally moving a releasingfor setting carriage the re- --quired distanceaccording to the iiumber of; digits in the figure to be printed; and, the Qother set of keys being usedifor actuating "the recording or indicating disk-operating f mechanism, and simultaneously looking all of the recordin movement, as fong as a key is depressed, said second set of keys being employed also "for actuating m'eansfor producing a lateral .45 and intermittent movement of a printing deivice or carriage, and theoperationof a triphamm'er for striking thefs pring controlled "printing characters mounted upon said carrings for? printing the desired figures 'iipon a'strip ofipaper. 1 v

The*inventin has .for its; further object \m metres simple and efiici ntly operating means'forsregillating and limiting 'the de- 5 oimihpression of the different keys ne of'the general cha'r or indicating disks against figs u in ex itione d set of keys whereby.

setting-carriage is also correspondingly limited andis arrested at the proper place so that the recording or indicating disk to the left-of the machine and corresponding to the number upon the depressed key of said first-mentioned 'set' of keys will first be op- ,erated by the depression ofany one of the keys'in said second-mentioned set of keys, andby the successive depressions of the keys .in said second-mentioned set of keys the said releasing or settiiig carriage moving laterally and intermittently from' left to right,

. so asto cause said carriage to stop in front of each recording and indicating disk, which disks ,are micces'sively operated in sequence from left to right, until the releasing or setting-carriage has moved in front of the first disk at the extreme right of the machine, when all of the actuated parts have returned to their normal initial positions.

Other objects of thisinvention not at this time more particularly enumerated will be clearly understood from the following detailed description of the present invention. With the various objects of the present invention in view, the. said invention consists, primarily, in the novel adding and rint- 1mg machine hereinafter set forth an the invention-consists, furthermore, in the sev- -'1 eral novel organizations and combinations of the various devices and their parts, as well as in the details of the construction of the said parts, all of which will be'more fully described inthefollowing specification, and thenfinally embodied in the clauses of the claims which are appended to and which form an essential part of this specification. The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a side'elevationrof an adding and printing machine, showing one embodiment of the principles of the present invention, the usual main .shell or casing with which the machine is provided being, how-- ever, omitted from said view.

Before setting forth in detail the particula) construction of the several devices and their parts which-{ embody 'the' 'prii1cipa;l features of the adding and 'prin tingmachine illustrated in the accompanying draw ings, I will first 'outline the general, characteristics of thejm'achine, in 'orderthat the relation of the principal devices and their parts to each other. more clearly understood.

The machine comprises a suitable base and a detachable casing, the latter, however, not bein shownin the accompanying drawings, an two sets =of key-levers, andth'eir 'indices, which are to. be'independently operated by the operator, and which sets of key-levers and-. keys for the sake of clearnessare hereinafter respectively designated as the spacing keys and. the digit-indicating eys. Then there is a laterally moving releasing of setting carriage, the'movement of which is produced from right toleft of the machine by the depression of one of the said spacing-levers, the movement of said releasing or setting can'iage regulated by'lao movement of the said registering or adding zontal rows, and vertically in a column, the

' 'dicati'ng k I the column "of figures can be printed upon," the strip of paperat the bottom-of theeolinitial macro-indicating positions after the and their sum-total or aggregate amount has also been produced upon the strip of paper.

,num r of operated registering or adding ing the correspondingly numbered digit-in- ,orcheck to the operator,-that the correct itotal-amount is being printed. The machine is alsoprovided j for returning all of the previously operated during its return-movemenhihe. said releasmovement of the disk is from the-indicatingspace 9 to 10, orfrom 99 to 100, or from 999 the corresponding --spacii1gkey which has been depressed,'the'sai d laterally moved releasing or setting 'ca'rria e releasing for its operatiofn; a'-'c'orrespon 1n and normally locked registering or adding disk. The number of such registering or adding disks is one more than the number of the spacing keys. These digit-indicating, key-levers actuate and operate a -su'ita le -mcchanism which determines the extent of the rotary disks, and the said digit-indicating keylevers also actuating and operating 'a print{ ing-mechanism for printing upon inf-"piece or strip of paper the desired numbersin horiaggregate of said column of numbers, when com leted, being exposedto view'flppon the disks, whereupon, by consecutively depress ey'levers, the total-amount? of umn of figures, Suitable mechanism is also provided for throwing the several registering or adding disks out oflopeiation, and simply causing the digit-indicating keylevers to actuate and ,operate the, rintingmechanism, which may be broughtinto operation at the time of printing the total amount at the'bottom of the column of numbers, so that the sum-total or aggregate amount will remain exposed to the view of the, operator, and thereby serve as a guide registering or adding disks to their normal desired numbers or'figures have been printed Thegmachlne is constructed, also, in such a manner, that during the depressions of the digit-indicating key-levers the said releasing or setting carriage i s intermittently or by a step-by-stepm'ovement returned from left to right of the machine to its'normal starting position, at rest, it being understood that ing or setting carriage is for the time being arrested in front of and with'uelatipn to the next lower and adiizceut registering 6r indicating disk, so jas'to permit of the successive rotary movements of the next succeeding disks, as will be clearly'\ evident. The several registering or indicating disks are also provided with suitable mechanism for producing the rotary movements of any two adjacent disks simultaneously, when the to 1000, and the like.
